Creator:: Aagaard, Jan Erik
Abstract:: In order to better understand the evolutionary patterns revealed by molecular markers, we studied genetic diversity and differentiation of populations and races of Douglas-fir using randomly amplified polymorphic DNA (RAPD) markers of nuclear and mitochondrial origin. We conducted a range-wide survey of RAPD diversity and differentiation, and compared RAPDs and...

Creator:: Abdel-Gadir, Abdelazim Yassin
Abstract:: The purpose of this study was to investigate variation in some intra-ring characteristics in juvenile and mature wood from two Douglas-fir genetic plantations established in 1912 by the U.S. Forest Service. The experimental material consisted of progeny from thirty families representing ten provenances (3 families per provenance) grown in two...

Creator:: Balduman, Lisa M.
Abstract:: Cold hardiness and phenology are important adaptive traits for perennial plant species in temperate climates. Timing of growth, dormancy, and associated cold acclimation and deacclimation represents a delicate balance between maximizing growth under favorable conditions and minimizing frost damage under unfavorable conditions. Geographic patterns of genetic variation in adaptive traits,...

Creator:: Hipkins, Valerie D.
Abstract:: To help understand the mechanisms of conifer chloroplast genome evolution, we characterized the nucleotide sequences of Douglas-fir (Pseudotsuga menziesiz) and Monterey pine (Pinus radiata) chioroplast DNA that are associated with a length mutation hotspot and inversion. The chloroplast DNA ofthese two conifers are characterized by shared large inversions that are...
